8 Claims. 1

This invention relates to improvements in coiled-spring beds, and moreparticularly to detachable legs useful in converting a conventionalcoiled-spring mattress of the open metallic frame type into a knockdownbed.

One object of this invention is to convert a conventional open framecoiled-spring mattress into a bed and back again at will.

Another object is a series of legs adapted for rapid attachment to anddetachment from the frame of an open coiled-spring mattres to form aknockdown bed.

Another object is a detachable leg construction of but few and simpleparts which is inexpensive sential to an understanding of the invention;

As best disclosed in Figs. 1 and 2, the bed II may consist ofconventional open coil coiledspring mattress having the conventionalopen coil coiled-spring mattress having the conventional angular baseframe I2, fashioned out of angle iron or'steel supporting a series ofspaced rows of horizontally spaced coiled-springs I3 attached to theupper angle-shaped frame of the bed II to complete acoiled-springmattress for any conventional type of bed mattress.

At suitably spaced intervals a series of leg assemblies I4, I4 aredetachably attached to the base frame [2. As best shown in Fig. 2, eachleg assembly I4 may consist of a wooden leg having a slotted guide plateI5 and an angle bracket I6 riveted to the head end of the wooden leg, bymeans of the rivets I8 and I9 passing through holes drilled in the headend of the leg, through which the rivets I8 and I9 may be inserted andthen permanently riveted in one of the oppositely disposed faces of theslotted guide plate I5. The slotted guide plate I5 and the angle bracketI6, are provided with holes arranged in horizontally spaced alignmentadapted to receive the shank of a screw bolt I1 which may be secured inplace by a suitable nut.

The base frame I2 is of angle iron, and includes an outwardly extendinghorizontal flange 45, and a depending vertical flange 45 Base frame I 2is adapted to be supported by the upper extremity of the leg I4 and itsvertical flange 46 nests in the slot 43 of the slotted guide plate I5,so that when the screw bolt I1 is inserted through both the anglebracket I6 and the slotted guide plate II, the 'nut may be screwed uponthe bolt to anchor the head end of the leg assembly I4 which now nestsin the angle defined by the conjunction of the flanges 45 and 46 of theangle-shaped base frame I2. The outwardly extending horizontal flange 45and the depending vertical flange 46, in conjunction, define an invertedL-shaped base frame I2.

The upper end of the angle bracket I6 is bent over at right angles toform the horizontally disposed portion 40 and the bifurcated fingers 4|,4|, which overlie the top edge face 41 of the wooden leg. The dependingvertical flange 45 of the inverted L-shaped base frame I2 nests in theslot 43 in the guide plate I5 and the horizontal flange 45 of base plateI2 lies between the guide plate I5 and the upstanding holed lug 42 ofthe angle bracket I6. The marginal side edges of the guide plate I5 areinwardly bent at right angles to the rest of the guide plate I5 to formthe horizontally spaced, vertically disposed ears 44, 44. The guideplate I5 and the horizontally spaced cars 44, 44 in conjunction define aU-shaped channel wherein the squared head of the wooden leg I4 nestswith a snug flt. The inner vertical edge face of the head end of the legI4 is rabbeted to conform to the shape of the slots 43, 43 in the guideplate I5, so as to allow the depending vertical flange 46 of base frameI2 to nest between the guide plate I and the ears 44, 44 and therabbeted side wall of the head end of the leg assembly I4. The shank ofthe screw bolt II rests upon the upper face of the outwardly extendinghorizontal flange 45 of the base frame I2, so that the more the screwbolt I1 is tightened in the threaded opening in the guide plate I5, themore securely the head of the leg assembly nests in the angular wallformed by the conjunction of the horizontal flange 45 and the dependingvertical flange 46, a

of the inverted L-shaped base frame I2, and the more securely theoutwardly extending horizontal flange 45 is anchored between the guideplate I5 and the upstanding holed lug 42.

By assembling four or more leg assemblies -I4 upon the angle-shaped baseframe I2 at spaced intervals so as to distribute the load evenly, theopen coiled-spring is converted into .a bed, adapted;;to support theconventional mattress, thus dispensing with the frame assembly of theconventional bed. By removing the leg assemblies I4, the bed may bequickly converted back into a conventional open coiled-spring mattressadapted to-be used upon any conventional type of'bed frame.

Figs. 3, 4 and 5 show a modified form of detachable leg assembly 20. aThe head of the leg is rabbeted' (Fig. 5') to accommodate the verticalflange 46 of the angle-shaped base frame I2. The leg is also drilledhorizontally to form a dowel socket 26 (Fig.5). Preferably the dowelsocket 26 does not pass completely through the leg, butterminates shortof the opposite face of the leg to provide a positioning stop 25. Asocket 24 is drilled; vertically downwards from the top face of the leg20, in alignment with the dowel socket 26, to form a screw socket 24which merges at the bottom with'the dowel socket 26.

A metal dowel pin 2Idrilled and tappedto receive two machinescrews 23 isinserted in the dowel socket 26, so that when the dowel pin M isinserted in the dowel socket 2 6 with the end of the dowel pin 2I inabutment with theposi- 'tioning stop 25, one of its tapped openings maybe aligned with the screw socket 24 to receive one of the machine screws23 which may be passed through one of the holes in the yoke '22 andscrewed into the tapped hole in the dowel pin 2|. When the angle-shapedbase frame I2 is properly seated upon the upper extremity of the leg 26,the-yoke 22 maybe placed across the horizontal face of the channelironso that the hole in the inner side of yoke'22 is in alignment with theinner tapped hole of the dowel pirrZI, whereupon a machine screw 23 maybefinserted through the hole in" the yoke 22 and screwed into the tappedopening in the dowel pin 21. When the rabbeted head end of leg 28 nestsproperly in the angle-shaped base frame'IZ and both machine screws 23are properly tightened in the dowel pin 2 I, the angle shaped base frameI2 will be effectively anchored to the head .end of the leg assembly 28.

The modified form shown in Figs. 6 and 7 includesa U-shaped clamp. 30adapted to straddle the head endof the legof the detachable leg assembly36. The. inner face of the head end of the leg-36 may be rabbet'edtoform a flush seat fortheangle-shaped base frame. I2 when thelatter isseated upon the head end of the leg 36 (see Fig. '7). The head end ofthe-leg 36 may also be. provided with a'half-yround .slot ex- 4, tendinghorizontally across the inner face of the leg to form a seat for thesemi-cylindrical tip of the U-shaped clamp 30. A half-round nut 3|female threaded at 33, is adapted to be seated 5 in the semi-cylindricaltip of the U-shaped clamp 30. The nut 3I may be separate from theU-shaped clamp 30, but is preferably spot welded or otherwisepermanently seated in the semicylindrical tip of the U-shaped clamp 30.The tips of the clamp 30 are provided with horizontally spaced alignedopenings 35 adapted to receive a machine screw 32 which may be fastenedin the female. threaded opening 33 of the halfround' nut 31. A hole isalso drilled through the head end of the leg 36 to receive a machinescrew '32; Thus, when the angle-shaped base frame I2 is properly seatedupon the head end of the leg 36 the head end of leg 36 nests in theangle in the frame I2, and the U-shaped clamp may be invertedover theangle-shaped base frame I2 .so that the upright legs of the clamp30,encompass the oppositely disposed-walls. of thehead end of the leg36, with the opening and the 25 female threaded opening '33 in alignmentwith the hole in the head end of the leg 36. The machine screw 32 isthen passedthrough the aligned holes and screwed into the female.

' frame I2,= the leg assemblies and the angleshapedbaseframe I2 willcooperate when secured together to form. a very rigidspring bed Woodenlegs give satisfactory results, but metal legs maybe substitutedifdesired. When wooden legs are used, suitable domes or glides 34 may beattached to the legsin the conventional way. Casters, rollers or otherconventional forms of devices may be substituted for the domes 34. r
